The size of a baby’s head is often related to neurological disorders, such as autism – which affects 1 in 88 children. Now, researchers at Duke University Medical Center have identified genes responsible for head size at birth by inserting human genes into zebrafish. The study is published online in the journal Nature. Nicholas Katsanis, Ph.D., Jean and George Brumley Jr. M.D…

Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we’ve had since high school genetics that DNA consists of only four bases. Now, researchers at Weill Cornell Medical College have made a discovery that once again forces us to rewrite our textbooks…

Researchers at the Indiana University School of Medicine have developed a test that can predict how likely an individual is to develop schizophrenia. The scientists combined data from several different types of studies in order to identify and prioritize a group of genes most associated with the disease…

Genes play a greater role in forming character traits – such as self-control, decision making or sociability – than was previously thought, new research suggests. A study of more than 800 sets of twins found that genetics were more influential in shaping key traits than a person’s home environment and surroundings…

Researchers at the University of Chicago have found an association between anxiety disorders and the gene that encodes Glyoxylase 1 (GLO1). However, the mechanism underlying this association is unclear. The most prevalent psychiatric diseases in the United States are anxiety disorders, which range from post-traumatic stress disorder to social phobia…

In a study published in Nature, researchers describe nine new genes that drive the development of breast cancer. This takes the tally of all genes associated with breast cancer development to 40. The team examined all the genes in the genomes of 100 cases of breast cancer…

Common variants of the ApoE gene are strongly associated with the risk of developing late-onset Alzheimer’s disease, but the gene’s role in the disease has been unclear. Now, researchers funded by the National Institutes of Health have found that in mice, having the most risky variant of ApoE damages the blood vessels that feed the brain…

What can a fish tell us about human brain development? Researchers at Duke University Medical Center transplanted a set of human genes into a zebrafish and then used it to identify genes responsible for head size at birth.

Researchers at Warwick Medical School have discovered a way of identifying which women are most at risk of postnatal depression (PND) by checking for specific genetic variants. The findings could lead to the development of a simple, accurate blood test which checks for the likelihood of developing the condition…

Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and “personalized medicine” tailored to the specific biochemistry of individual patients. The device, which could be several hundred times more sensitive than other biosensors, combines the attributes of two distinctly different types of sensors, said Muhammad A…
